Best Way to do Elevation Dimensions?

[Miranda]

The dimensioning tools in Elevation views don't seem to work well for me. They don't want to snap where I want them. The workarounds I have tried:

1) Draw CAD lines where needed and dimension between them (cumbersome and hard to be accurate)
2) Export dxf, import into Autocad and use Autocad for final drawings (hate to use a separate program)
3) Export dxf, import same dxf back into CA and dimension in CA (This emulates the Premier "convert to CAD lines" option)

I'm sure there is a better way, any suggestions?
